A lot of vehicles, particularly high-end ones, require that only the dealer be allowed to make new keys.

The method to do this yourself is different from manufacturer to manufacturer. It typically involves inserting the spare key that works into the ignition and manipulating it (in accordance with the directions in the owner's manual) until your car is in programming mode. You'll need to be quick to complete the procedure, since it only lasts a few seconds before your car leaves the mode.
